It's impossible to have a normal friendship or relationship with that kind of money. Best position is lower middle class. Tons of friends, you know your wife loves ya. It's lit.
I was at a club in Ginza last night, met a guy from Sweden who's been in Japan for 20 years. I'm sure he's got plenty of money, great job, economic freedom whatever, but he was ALONE.
One could argue that it's not really possible to have a real close relationship unless you're secure with yourself. People who aren't always take a suspicious/defensive posture.
I worked at a ramen restaurant in Chicago for a year for minimum wage. The Mexican dishwasher ladies were always smiling and laughing. Why? Because REAL wealth is family and friends.
